Multi-domain spectral method for Kerr spacetimes: a hyperboloidal Teukolsky -mode solver for self-force computations
Brad Cownden, Rodrigo Panosso Macedo, Christiana Pantelidou +2
We solve the frequency-domain, -mode Teukolsky equation for the spin-weight Weyl scalar sourced by a point mass on a circular, equatorial orbit around a Kerr black…
Turbulent gravitational wakes
Giulio Taiocchi, Christiana Pantelidou, Miguel Zilhão
We construct turbulent gravitational wakes in asymptotically AdS spacetimes by solving the full non-linear Einstein equations in the characteristic formulation. Specifically, w…
Bilinear products and the orthogonality of quasinormal modes on hyperboloidal foliations
Marica Minucci, Rodrigo Panosso Macedo, Christiana Pantelidou +1
We explore the properties of bilinear products for black-hole quasinormal modes (QNMs) formulated on hyperboloidal foliations. We find that, although QNM solutions are smooth and f…
Transients in black hole perturbation theory
Jérémy Besson, Javier Carballo, Christiana Pantelidou +1
Black hole quasinormal modes arise as eigenmodes of a non-normal Hamiltonian and consequently they do not obey orthogonality relations with respect to commonly used inner products,…
Non-modal effects in black hole perturbation theory: Transient Superradiance
Javier Carballo, Christiana Pantelidou, Benjamin Withers
We study the non-modal stability of black hole spacetimes under linear perturbations. We show that large-amplitude growth can occur at finite time, despite asymptotic decay of line…
Spinning particles near Kerr black holes: Orbits and gravitational-wave fluxes through the Hamilton-Jacobi formalism
Gabriel Andres Piovano, Christiana Pantelidou, Jake Mac Uilliam +1
Extreme mass-ratio inspirals are among the key sources of gravitational waves for the Laser Interferometer Space Antenna space-based gravitational-wave detector. Achieving sufficie…
The pseudospectra of black holes in AdS
Brad Cownden, Christiana Pantelidou, Miguel Zilhão
We study the stability of quasinormal modes (QNMs) in electrically charged black brane spacetimes that asymptote to AdS by means of the pseudospectrum. Methodologically, we adopt i…
Black hole excited states from broken translations in Euclidean time
Christiana Pantelidou, Benjamin Withers
We prepare an excited finite temperature state in SYM by means of a Euclidean path integral with a relevant deformation. The deformation explicitly breaks imaginary-ti…
Thermal three-point functions from holographic Schwinger-Keldysh contours
Christiana Pantelidou, Benjamin Withers
We compute fully retarded scalar three-point functions of holographic CFTs at finite temperature using real-time holography. They describe the nonlinear response of a holographic m…
Holographic Dissipation from the Symplectic Current
Aristomenis Donos, Polydoros Kailidis, Christiana Pantelidou
We develop analytic techniques to construct the leading dissipative terms in a derivative expansion of holographic fluids. Our basic ingredient is the Crnkovic-Witten symplectic cu…
Higgs/Amplitude Mode Dynamics From Holography
Aristomenis Donos, Christiana Pantelidou
Second order phase transitions are universally driven by an order parameter which becomes trivial at the critical point. At the same time, collective excitations which involve the…
Gravitational quasinormal modes for Lifshitz black branes
Tomas Andrade, Christiana Pantelidou
We study the scalar and vector channels of gravitational quasinormal modes for Lifshitz black branes emerging in Einstein-Maxwell-Dilaton and Einstein-Proca theories in four and fi…
Dissipation in Holographic Superfluids
Aristomenis Donos, Polydoros Kailidis, Christiana Pantelidou
We study dissipation in holographic superfluids at finite temperature and zero chemical potential. The zero overlap with the heat current allows us to isolate the physics of the co…
Incoherent hydrodynamics of density waves in magnetic fields
Aristomenis Donos, Christiana Pantelidou, Vaios Ziogas
We use holography to derive effective theories of fluctuations in spontaneously broken phases of systems with finite temperature, chemical potential, magnetic field and momentum re…
Quasinormal modes in charged fluids at complex momentum
Aron Jansen, Christiana Pantelidou
We investigate the convergence of relativistic hydrodynamics in charged fluids, within the framework of holography. On the one hand, we consider the analyticity properties of the d…

We study black hole solutions of Einstein-Maxwell theory coupled to a charged scalar field that are holographically dual to a conformal field theory with a non-vanishin…
Driven black holes: from Kolmogorov scaling to turbulent wakes
Tomas Andrade, Christiana Pantelidou, Julian Sonner +1
General relativity governs the nonlinear dynamics of spacetime, including black holes and their event horizons. We demonstrate that forced black hole horizons exhibit statistically…

Hydrodynamics of broken global symmetries in the bulk
Aristomenis Donos, Daniel Martin, Christiana Pantelidou +1

Holographic transport and density waves
Aristomenis Donos, Christiana Pantelidou
We consider transport of heat and charge in holographic lattices which are phases of strongly coupled matter in which translations are broken explicitly. In these systems, we study…
Large D holography with metric deformations
Tomas Andrade, Christiana Pantelidou, Benjamin Withers
We consider Einstein gravity in AdS in the presence of a deformed conformal boundary metric, in the limit of large spacetime dimension. At leading order we find a new set of effect…
